The understanding of both natural and human impact on geo- and ecosystems over long time scales is crucial for calibrating and improving predictions of future climate and environmental change based on different forcing scenarios.
The Department of Geoscience has a long history of achievements in reconstructing past environmental and climatic changes, spanning most geographical regions across the globe with special focus on the Arctic. In particular, the fact that climate change is driven by complicated non-linear feedback mechanisms requires long time series of multiple proxies recorded in geological archives to elucidate the processes causing climate change.
We explore these themes by analyzing marine and terrestrial paleo-archives, and by numerical modelling of glaciers, ice sheets, and sea level. For details we refer to the specific research groups and centres.
